7.Extraction method of the magnetoencephalography somatosensory evoked signals based on the MP decomposition
China Medical Equipment 2014;(5):48-51
Objective:Matching pursuit algorithm(MAP),for its good parametric characterization, is applied in Magnetoencephalography(MEG) to study time-frequency distribution. Methods:This paper proposes to apply a high-resolution time-frequency analysis algorithm, the matching pursuit (MP), to extract detailed time-frequency components of SEF signals. Results: Experimental results on cortical SEF signals of several normal subjects show that a series of stable SEF time components can be identified using the MP decomposition algorithm. Conclusion:This study shows that there is a set of stable and minute time-frequency componentsin SEF signals, which are revealed by the MP decomposition. These stable SEF components have specific localizations in the time domain and may provide a reliable index for clinical research of brain function and brain disease pathogenesis.
8.Prediction of acute kidney injury complicated by sepsis with sTREM-1 and NGAL as early marker
Chinese Journal of Nephrology 2013;29(6):423-428
Objective To determine whether triggering receptor expressed on myeloid cells-1 (sTREM-1) and urinary neutrophil gelatinase-associated lipocalin (NGAL) were early biomarkers of acute kidney injury (AKI) secondary to sepsis.Methods A total of 141 eligible patients were enrolled in this prospective study.Blood and urine samples were collected at different time points as soon as sepsis was diagnosed.The concentrations of serum creatinine (Scr),urine sTREM-1 and NGAL were measured.According to AKI criteria,patients were divided into the AKI group and non-AKI group.Dynamic changes of levels of Scr,urine sTREM-1 and NGAL were observed in two groups.The receiver operating characteristic curves were used to evaluate the early diagnostic value of urine sTREM-1 and NGAL.Results Among 141 septic patients,44 (31.2%) cases had concomitant AKI.Twenty four hours after sepsis diagnosed,the level of Scr rose to 1.91 times of the baseline [(140.5±13.6) vs (82.6± 15.3) μmol/L,P < 0.05],which met the diagnostic criteria of AKI.In the AKI group,urinary concentrations of sTREM-1 and NGAL at 8 h after the diagnosis of sepsis began to rise significantly from baseline [(100.5±17.4) vs (38.9± 14.7) ng/L; (144.6±51.9) vs (56.2±43.8) μg/L,both P < 0.05].And at the following time points,urinary concentrations of sTREM-1 and NGAL were significantly higher than the baseline levels and that of the non-AKI group (all P < 0.05).At 8 h time point,thearea under the curve of urine sTREM-1 was 0.877 (95%CI 0.756-0.914),the sensitivity was 89.1% and specificity was 82.0% with a cutoff value of 70 ng/L.At 8 h time point,the area under the curve of urine NGAL was 0.862 (95% CI 0.703-0.958),the sensitivity was 87.4% and specificity was 85.5% with a cutoff value of 90 μg/L.Conclusions Urinary concentrations of sTREM-1 and NGAL at 8 h time point after the diagnosis of sepsis have predictive value for AKI and their diagnostic time is much earlier than that of Scr.Therefore,urinary sTREM-1 and NGAL can be used as early biomarkers of septic AKI.

Chinese Journal of Tissue Engineering Research 2013;(42):7475-7480
BACKGROUND:The appropriate choice of orthoses based on hemiplegic patient’s condition can improve motor function recovery in stroke patients.
OBJECTIVE:To review the motor function recovery of stroke patients with hemiplegia wearing different types of orthoses.
METHODS:Application of different types of orthoses in hemiplegic patients was reviewed through access to literature, as wel as effects of a variety of orthoses on the recovery of motor functions in hemiplegic patients.
RESULTS AND CONCLUSION:Orthoses can reduce limb muscle tension and muscle spasms, and improve motor function and overal daily living skil s in stroke patients with hemiplegia, which play a variety of roles, including stable support, fixed protection, correction of deformity and functional compensation. However, the long-term therapeutic effect of orthoses cannot be verified because of fewer cases, shorter time for therapeutic observation, and the lack of long-term fol ow-up. It is necessary to perform long-term fol ow-up for the verification of long-term efficacy of orthoses. Meanwhile, the appropriate timing for removal of orthoses needs further study.
10.Traditional Chinese medicine intervention for stem cell transplantation in the treatment of cerebrovascular diseases
Chinese Journal of Tissue Engineering Research 2013;(49):8615-8620
BACKGROUND:Stem cells under appropriate conditions can be induced to differentiate into neuron-like cells. Chinese herbs can function in cellproliferation and differentiation.
OBJECTIVE:To investigate the interventional effects of traditional Chinese medicine on stem celltransplantation in the treatment of cerebrovascular diseases.
METHODS:Experimental studies concerning traditional Chinese medicine intervention for stem celltransplantation were retrieved and analyzed. Under specific conditions, stem cells can proliferate in vitro in a suspended or monolayer manner, and can be potential y induced to differentiate into neurons, oligodendrocytes and astrocytes, thereby providing basis for stem celltransplantation in the treatment of cerebrovascular diseases. We observed expressions of nestin, glial fibril ary acidic protein, and microtubule-associated protein expression for analysis of stem cellproliferation and differentiation.
RESULTS AND CONCLUSION:Baicalin or Astragalus saponin Ⅳ can stimulate stem cells to differentiate into nerve cells in vitro. Naomaitong or danshen combined with bone marrow mesenchymal stem celltransplantation can promote neurological recovery from cerebrovascular diseases in rats. Buyang Huanwu Decoction can significantly promote the proliferation of neural stem cells in the subventricular zone and neurological recovery after cerebral ischemia. Chinese herbs, such as Zhichan Decoction and Panax notoginseng, can promote survival of transplanted cells and prevent most cellapoptosis in the stem celltherapy for treatment of Parkinson’s disease. Therapy of benefiting qi and elevating yang or ginsenosides Rg1 combined with stem celltherapy can improve memory ability of dementia rats. Traditional Chinese medicine exerts a catalytic role in the stem celltherapy for cerebrovascular diseases.
